Our 15x salvia extract contains 54mg of pure salvinorin-A per gram of extract which is extracted from the plant and then redeposited back onto dried leaves. Our skilled chemists use a standardized method, which costs a little more than non-standardized methods, but means you will find no extra plant matter which can be harmful to your lungs. Salvia Extract is not a liquid. This dosage has been described as very potent, and we recommend that you exercise caution when using this product.
